雙語：蛟龍號在中國南海完成第四次深潛！

Jiaolong, China』s manned submersible, conducted its fourth dive Sunday around the Zhenbei Seamount in the South China Sea.

深潛器蛟龍號於周日在南海的珍貝海山完成第四次深潛。

Jiaolong stayed underwater for eight hours in its fourth dive in the second stage of China』s 38th ocean scientific expedition, which will last until May 13, authorities said Monday.

官方在周一透露，在海洋科學考察第二階段中，蛟龍號第四次深淺在水下時間長達八小時，而這次考察將一直持續到五月十三號。

The maximum depth of the dive was 1,101 meters beneath the sea surface, where it retrieved a number of basalt samples.

這次深淺的最深處是海平面以下1101米，蛟龍號在那裡取回了一些玄武岩的樣本。

In the meantime, it collected a 0.7-kilogram sample of foraminifer grit at the depth of 630 meters, and brought back samples of sediments and seawater near the seabed as well as high-definition photos and video footages.

與此同時，它在630米深處收集了0.7千克的有孔蟲沙樣本，並帶回了海底附近的沉積物和海水樣本以及高清晰度照片和視頻片段。

"We have also caught sight of corals, sea lilies, anemones, and large fishes like sharks above 420 meters," said Yang Gang, a senior engineer on board the submersible.

潛水器上的高級工程師楊剛說：「我們還看到了珊瑚，海莉，海葵和超過420米的大型魚類，比如鯊魚。」

Yang said that the new discoveries could shed new light on the study of the South China Sea』s formation and evolution, biodiversity, and the cause of the seamount chain in the area.

楊剛說到，這些新的發現可以進一步闡述南海的形成與演變、生物的多樣性和海山鏈形成的原因。

Instead of using trawling as a sampling method, Jiaolong is able to conduct refined sampling mission and obtain ample samples, said Shi Xuefa, a researcher with the State Oceanic Administration.

國家海洋局的研究員石學法說到，除了捕撈式的採集方法，蛟龍號可以精細抽樣任務並獲得豐富的樣本。

Jiaolong has completed four dives in the South China Sea within five days. The submersible has went through full maintenance on Monday, including its propelling and electrical systems.

蛟龍號五天內在南海完成了四次深淺。這艘深潛器在周一做了全面維護，包括推進系統和電力系統。

"The 38th ocean scientific expedition will be the furthest and longest voyage for Jiaolong in terms of distance and time, "said Wu Changbin, general commander of the second stage of the expedition. "Jiaolong will also complete the largest number of tasks since its operation."

「第38次海洋科學考察在距離與時間方面是蛟龍號目前為止最遠最深的航行，」考察第二階段總司令吳昌斌說「蛟龍號也將完成從投入使用以來最多的任務」 。

The 38th oceanic scientific expedition started on Feb. 6. Jiaolong completed a dive in the northwestern Indian Ocean earlier this year in the mission』s first stage. It will also conduct surveys in the Yap Trench and the Mariana Trench in the third stage.

在第三階段，它也將在雅普海溝和馬里亞納海溝進行調查。

Named after a mythical dragon, Jiaolong reached its deepest depth of 7,062 meters in the Mariana Trench in June 2012.

蛟龍號以神話傳說的龍來命名，該深潛器於2012年6月在馬里亞納海溝創下了其目前最深記錄：7062米。
